AngularJS Nested View

Edited on 10/05

I've been following this anjularjs and asp.net tutorial. I am trying to add some additional things on my own, but I am stuck. I am getting a JSon object from the server, and I am trying to display the object's content to the client. The issue is that I am getting [object Object] on the client side when I am expected to see a list of ID, Name, and Password. What am I missing here?

//The controller

  myApp.controller('userController', function ($scope,$http /*UserService*/) {
      //  $scope.Users = [];
        $http.post('/Templates/ListUsers',{ id : 0})
        .success(function (data) {
            // $scope.Users = data.data;
            if (data.Ok) {
                $scope.Users = data.data;
                console.log($scope.Users);
            }
        }).error(function(error){
            console.log(error);
        });

//The form where the data is supposed to display. 
<div class="row">
       <div class="form-group">
           <li ng-repeat="x in Users"> 
**//I am iterating through the users, 
//so I was not expected to see [object Object]**
               {{ x.ID, x.Name, x.Password  }}
           </li>
       </div>
   </div>   

//The JSON object in the console window:
[{"ID":1,"Name":"Name1","Password":"Password1"},
{"ID":2,"Name":"Name2","Password":"Password2"},     
{"ID":3,"Name":"Name3","Password":"Password3"},
{"ID":4,"Name":"Name4","Password":"Password4"}]

The index page with AngularJS and Angular-Route Version 1.4.7

<!DOCTYPE html>
<html lang="en" ng-app="myApp">
  <head>
    <title>AngularJS Routing example</title>
      <base href="/">

  <body>

    <div class="container">
        <div class="row">
        <div class="col-md-3">
            <ul class="nav">
                <li><a href="/NewOrder"> Add New Order </a></li>
                <li><a href="/ShowOrders/123"> Show Order </a></li>
               <div ng-controller="CalculatorController">
                <li><a href="/Calculator">Calculator</a></li>
              </div>
                <li><a href="/Users">Add Users</a></li>
            </ul>
        </div>
        <div class="col-md-9">
            <div ng-view></div>
        </div>
        </div>
    </div>

//Updated on 10/06:

Instead of using CDN references, I downloaded AngularJS and AngularJS-Route 1.4.7 and referenced them instead. When I ran the application, it simply display the entire JSON object.

[HttpGet]
    public JsonResult ListUsers()
     {
       return View();
     }

 [HttpPost]
        public JsonResult ListUsers(int id=0)
        {
            try
            {
                List<User> listUser = new List<User>()
            {
                new User{ ID= 1, Name = "Name1", Password="Password1"},
                new User{ ID= 2, Name = "Name2", Password="Password2"},
                new User{ ID= 3, Name = "Name3", Password="Password3"},
                new User{ ID= 4, Name = "Name4", Password="Password4"}
            };

                return Json(new { Ok = true, data = listUser, message = "Success" }, JsonRequestBehavior.AllowGet);
            }
            catch (Exception ex)
            {
                ex.ToString();
                return Json(new { Ok = false, data = "", message = "Failure" }, JsonRequestBehavior.AllowGet);
            }
        }

The Route Added

  routes.MapRoute(
                name : "listUsers",
                url : "Templates/ListUsers/{id}",
                defaults : new { controller = "Templates", action = 
 "ListUsers", id = UrlParameter.Optional });

Updated on 10/07

I noticed that changing the view to return a view and hard coding the json object to the users' controller works. Because of that, I added another method with a [HttpPost] annotation, changed the $http.get to $http.post, and added the ID parameter. Also, I modified the route to have an optional id so that '/Templates/ListUsers' will work so it '/Templates/ListUsers/1'. I was expected $http.post with a parameter of 1 to redirect to method with the HttpPost annotation, but it did not happen. I am not sure that things are making sense to me at this point. I am reading the $http.post again and see if I can see where I made the mistake.

Finally, I got it to work although another issue pops its head up. I removed the default route and added a catch all route.

 routes.MapRoute(
                name : "catchAll",
                url : "{*Url}",
                defaults : new { controller = "Templates", action = 
 "ListUsers", id = UrlParameter.Optional });

By coincidence, I also remove the comment for the route below

 routes.MapRoute(
                name : "Default",
                url : "{controller}/{action}/{id}",
                defaults : new { controller = "Home", action = 
 "Index", id = UrlParameter.Optional });

I did a post, and it worked. If I commented the catch all route, it worked fine. However, the catch all route did not appear to be doing anything at this point because refreshing the page returned 404. If I moved the catch all above the default route, it stopped working too. I still have to figure this part out now.

Your base template should have a ui-view to hold the preLogin partial view, else angular won't know where to put it. You can even write the template itself on the base template, or make it a directive, and then show/hide based on certain criteria in your base controller.
